I can only assume that COD: BO requires a newer cios than 17 so you will either need to install a more recent cios like 20b to a slot other than 249 and just change what ios you load the game with, or you will just have to give up triiforce so that you can install a later cios than 17 to 249. The choice is yours.

Ok DigtlLogic this is how I got both to work. Install CIOS249 Rev 17 in slot 249, this way you can still use Triiforce as before. Next install CIOS249 Rev 20b into slot 250 instead of the default slot 249. Use the 250 version of Wiiflow to launch COD Black Ops. The game is playable all the way through with no glitches (except bugs already in the game). However I cannot get multiplayer to work, which may just be my setup, and I have to reset the Wii manually when exiting the game.

It is never safe to do anything with wads unless you have a backup of the NAND.

Hope this helps you with your COD and Triiforce dilemma.

hry mate check the black ops guide you need toset up another profile and the second one works perfectly, no one knows why but it works

I've followed this guide to the T, and got my WiiWare/VC games to work on USB, (system booted from an SD). My only problems are:

- Any game freezes on the Home pause screen when the Home button is pressed, and the system needs to be hard reset
- If the power button is pressed on the WiiMote, the Wii will appear to turn off, but the Power button is still green, and the Wiimote indicators flash

Has anyone ran into these problems? I'm glad I got the games working, but I'd like to quit the apps without feeling like I pulled the ac adapter right out of the wall everytime I want to turn it off or play something else! :/
